The LTM8053 is a 40VIN, 3.5A continuous, 6A peak step-down µModule® (power module) regulator. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.4V to 40V, the LTM8053 / LTM8053- 1 supports an output voltage range of 0.97V to 15V and a switching frequency range of 200kHz to 3MHz, each set by a single resistor. Only the input and output filter capacitors are needed to finish the design. The LTM8053-1 can operate in forced continuous mode.

The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8053 / LTM8053-1 is packaged in a thermally enhanced, compact over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8053 / LTM8053-1 is RoHS compliant.

Product Detail

The Quad-MxFE System Development Platform contains four MxFE software defined, direct RF sampling transceivers, as well as associated RF front-ends, clocking, and power circuitry. The target application is phased array radars, electronic warfare, and ground-based SATCOM, specifically a 16 transmit/16 receive channel direct sampling phased array at L/S/C band (0.1 GHz to ~5GHz). The Rx & Tx RF front-end has drop-in configurations that allow for customized frequency ranges, depending on the user’s application.

The Quad-MxFE System Development Platform highlights a complete system solution. It is intended as a testbed for demonstrating multi-chip synchronization as well as the implementation of system level calibrations, beamforming algorithms, and other signal processing algorithms. The system is designed to mate with a VCU118 Evaluation Board from Xilinx®, which features the Virtex® UltraScale+ XCVU9P FPGA, with provided reference software, HDL code, and MATLAB system-level interfacing.

In addition to the Quad-MxFE Digitizing Card, the kit also contains a 16Tx / 16Rx Calibration Board that is used to develop system-level calibration algorithms, or otherwise more easily demonstrate power-up phase determinism in situations pertinent to their own use case. The Calibration Board also allows the user to demonstrate combined-channel dynamic range, spurious, and phase noise improvements and can also be controlled via a free MATLAB add-on when connected to the PMOD interface of the VCU118.

The system can be used to enable quick time-to-market development programs for applications like:

  • ADEF (Phased-Array, RADAR, EW, SATCOM)
  • Communications Infrastructure (Multiband 5G and mmWave 5G)
  • Electronic Test and Measurement

LTM8053 Demo Board | Buck μModule Regulator, 5.6V ≤ VIN ≤ 40V, VOUT = 5V @ 3.5A

Product Detail

Demonstration circuit 1934A is a 40V, 3.5A step-down μModule® regulator featuring the LTM8053. The demo board is designed for 5V output from a 5.6V to 40V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The user adjustable features of the LTM8053 such as output voltage, switching frequency, soft-start, and power good can be changed on DC1934A simply by modifying the appropriate resistors and/or capacitors. Two or more LTM8053s can be paralleled to share load current equally.
